Personalized video interjections based on learner model and learning objective

ABSTRACT

Personalized video interjections based on a learner model and a learning objective. A method for adding interjections to a video includes analyzing the content of a plurality of videos based on a set of learning objectives, generating and storing educational content metadata on a timeline for the videos, selecting a video based on a user specific learning objective, determining types of video interjections using an analytics engine that compares a user learner model, the user learning objective and the metadata, determining a location for the video interjections using the analytics engine that compares the user learner model, the learning objective, the metadata and timeline, generating a video interjection for each video interjection type and inserting the video interjections into the video at the determined locations.

BACKGROUND OF THE INVENTION

This disclosure is directed to computers and computer applications, and more particularly to computer-implemented methods and systems for generating personalized video interjections based on a learner model and a learning objective and inserting the personalized video interjections into a video at locations in the video to maximize learning.

Computer based adaptive learning solutions have been shown to be effective. However, automated tutoring systems can be much more effective if the learning is interactive and participative. Videos can be quite an engaging medium for knowledge delivery, but effective learning requires the video to have two way interaction. However, interactive engagement does not directly translate to learning, as the learner often can skip over content that they do not understand and still remain engaged since the rest of the content is sufficient for them to understand the overall context.

Current video-based knowledge delivery solutions are one-way, even though they contain significant useful knowledge. The few solutions that include two-way interactions are not personalized to a learner. Instead, typical adaptive learning solutions have specific predetermined interjections that are used equally for all learners without an understanding of the learner's specific learning objective or learning level.

SUMMARY OF THE INVENTION

One embodiment of a computer implemented method for adding interjections to a video includes the steps of storing a plurality of videos having content, analyzing the content of each the plurality of videos based on a set of learning objectives to generate educational content metadata and storing the educational content metadata on a timeline for each of the plurality of videos. The method also includes the steps of receiving a specific learning objective for a user, selecting one of the plurality of videos based on the received user specific learning objective and automatically determining one or more types of video interjections for the selected video using an analytics engine configured to compare a learner model for the user, the user specific learning objective and the educational content metadata of the selected video. The method also includes the step of automatically determining a location for each of the one or more determined types of video interjections using the analytics engine configured to compare the learner model for the user, the user specific learning objective, and the educational content metadata and timeline of the selected video. The method also includes the steps of generating a video interjection for each of the one or more determined video interjection types and inserting the one or more generated video interjections into the selected video at the respective determined location.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The present disclosure is directed to computer implemented methods and systems for making videos participative, personalized and interactive. In some embodiments, the learning process is personalized to learners based on learner models built over multiple experiences and interactions with a variety of learning solutions. In some embodiments, the methods and systems test the receptive and productive knowledge skills of the learner through interactions and assessments that are appropriate to the specific learner's learner model.

Interjection activities in the videos ensure that the student can participate in the learning more actively. Today, most video activities have a fixed point of interjections based on a concept being tested. The methods and systems of the present disclosure provide technological improvements over the prior solutions by the use of cognitive computing and data analytics to dynamically determine the type of interjections and the point of interjections based on the learner model of the user and the learning objective of the user.

FIG. 1 is one embodiment of a system 10 for adding interjections to a video. The system includes an ingestion and tagging module 12 having a storage 14 that stores a plurality of videos having content. The ingestion and tagging module 12 uses video analytics to analyze the content of each of the plurality of videos based on a set of learning objectives and generates educational content metadata for each of the plurality of videos. The educational content metadata is stored in a storage 16 on a timeline for each of the plurality of videos. The system 10 also includes an analytics engine 18 having an interjection orchestrator 20 and a micro-activity generator 22.

The interjection orchestrator 20 receives a specific learning objective for a user and selects one of the plurality of videos based on the received user specific learning objective. The interjection orchestrator 20 automatically determines one or more types of video interjections for the selected video. The interjection orchestrator 20 uses cognitive computing techniques to compare a learner model 24 for the user, the user specific learning objective and the educational content metadata of the selected video. In one embodiment, appropriate interjections are determined based on matching learning words and the metadata. In one embodiment, the matching is based on a web of words 26. The web of word 26 is a data structure that stores the semantic relationships between words. One example of the web of words 26 is the ConceptNet™ knowledge graph. In one embodiment, the learner model 24 is projected on the word web. In one example, for each word in the web of words 26, the learner's mastery of the word is determined from the learner model and the web of words 26 will indicate different levels of mastery for each word.

Different types of interjections may include, reinforcement, multiple choice questions, a user activity or any other learning types that may be presented on a video. For example, the types of interjections can be coaching instructions (did you see how big that bird was), teaching instructions (a bird is an animal, just like the cat you have at home) or assessment (which of the following are birds).

The interjection orchestrator 20 also automatically determines a location for each of the one or more determined types of video interjections using the cognitive computing techniques to compare the learner model for the user, the user specific learning objective, and the educational content metadata and timeline of the selected video.

The learner model is a computer program that maintains a mastery for each learning objective for the user. In one embodiment, the learner model 24 is a data structure that includes information about the user related to the users learning capabilities and knowledge with respect to a plurality of learning objectives. One example of a learner model 24 is the Open Learner Model (OLM). The OLM is a tool that visualizes an individual's current understanding of a topic, and/or their level of competency. The learner model updates as the student learns, and the data that lies behind the model can come from a variety of sources, such as outcomes of teacher or student self-assessment, or computer-based learning interactions. Learner models are built over time, present the most up to date information about student competency, and allow teachers and students to easily identify strengths and areas of difficulty. The learner model 24 may be generated using Watson Enlight™ or Watson Element™.

The micro-activity generator 22 generates a video interjection for each of the one or more determined video interjection types using the learning objective, the learner model and the education content metadata. In one embodiment, the micro-activity generator 22 matches words of the user specific learning objective with educational content metadata of the selected video based on the web of words 26. In one example, multiple choice questions are generated around facts, relationships and attributes by comparing the learner model and the education content metadata.

The analytics engine 18 then inserts the one or more generated video interjections into the selected video at the respective determined location to create the new interactive video 28 with the interjections.

In one embodiment, the system 10 dynamically adjusts the learner model based on video interactions of the user in response to a video playback of the selected video with the inserted one or more generated video interjections. Use interaction interface records activity of the user in response to the video playback of the selected video with the inserted video interjections. Learning assessment module 32 analyzes the user interactions and inputs the analysis to the learner model 24. The learner model 24 automatically adjusts based on the new inputs from learning and assessment module 32 and the interjection orchestrator 20 dynamically changes the one or more types of video interjections based on the adjusted learner model.

As shown in FIG. 2, in one embodiment, the interjection orchestrator 20 receives a specific learning objective for a user from learning objective selection module 34. The selection may be made by the user or an educator via a user interface or other known means from a list a preset objectives. The interjection orchestrator 20 includes a personalization video selection module 36. Based on the received learning objective, the personalization video selection module 36 selects an appropriate video for learner. The personalization video selection module 36 may have as inputs one of more of learner videos 38 previously watched for the received learning objective, learner previously favored videos 40 across other learning objectives and other favored video 42 s across cohorts of the learner. A learning objective can have multiple learning videos that may be appropriate. The personalization video selection module 36 performs cognitive computing on the inputs to select the right one for the learner.

The interjection orchestrator 20 also includes personalized interjections module 44. The personalized interjections module 44 has as inputs the educational metadata 16 and the learner model 24. The interjection types and locations can differ from learner to learner. The types and locations can differ based on system knowledge of the learner for same video.

The micro-activity generator 22, in one embodiment, may have an interjections for active listening mode 46. In the active listening mode, active listening interjections are generated that gauge the attention of the learner and try to engage the learner if they are not engaged. The micro-activity generator 22 may also have an interjections for contextual assessment mode 48. In the contextual assessment mode, interjections are generated to assess and reinforce the depth of learner knowledge in the learning objective.

FIG. 3 is a flow diagram of one embodiment of a computer implemented method for adding interjections to a video. The Method includes step S100 of storing a plurality of videos having content, step S102 of analyzing the content of each of the plurality of videos based on a set of learning objectives, step S104 of generating educational content metadata for each of the plurality of videos and step S106 of storing the educational content metadata on a timeline for each of the plurality of videos. The method further includes step S108 of receiving a specific learning objective for a user and step S110 of selecting one of the plurality of videos based on the received user specific learning objective. The method also includes step S112 of automatically determining one or more types of video interjections for the selected video using an analytics engine configured to compare a learner model for the user, the user specific learning objective and the educational content metadata of the selected video and step S114 of automatically determining a location for each of the one or more determined types of video interjections using the analytics engine configured to compare the learner model for the user, the user specific learning objective, and the educational content metadata and timeline of the selected video. The method further includes step S116 of generating a video interjection for each of the one or more determined video interjection types and step S118 of inserting the one or more generated video interjections into the selected video at the respective determined location. IN one embodiment, the method also includes step S120 of dynamically adjusting the learner model based on video interactions of the user in response to a video playback of the selected video with the inserted one or more generated video interjections and dynamically changing the one or more types of video interjections based on the adjusted learner model. For example, based on the learner's competency level of each word, the interjection locations and types are changed dynamically in the video. In one embodiment, the video viewing can be initially uninterrupted, and then the video is played back again to have the learning moments at specific points. In one embodiment, the number of such micro-learning moments is restricted to a threshold to avoid making the video viewing itself unpleasant. E.g. 1 interruption in 5 minutes.

In one exemplary embodiment, the system and method disclosed herein may be used when the learning objective is vocabulary learning. Videos are important for vocabulary tutoring since it can explain a word using variety of examples and activities. Just viewing a video does not ensure that the learner was engaged with the video and has learned the word. The learner model is in one example something that has a list of all the words and the level of mastery for each one per learner. There could be many words unfamiliar to a learner, the learning interjection will focus on one of the words.

In one such example, the each word, the learner's score and number of attempts to respond indicating knowledge of the word are: Arachnid, 0.45, 10; Amphibian, 0.4, 5; Adopt, 0.0001, 0; Pizza, 0.92, 5. Mastery of the word may be stored as a range. For example, 0.9 and higher (max of 1.0) means that the word is mastered, while 0.4-0.9 means the learner is working on it, it is in the learner's working set and below 0.4 means the learner is just starting to learn it or struggling with the learn the word.

The a video interjection may include where the learner is required to perform an action such as tapping on the screen immediately when they hear a particular word. The interjection may be where the learner is required to select a set of representative pictures from the screen for which they have heard in utterance in speech. The interjection may be where the learner is asked an assessment question around a word just after the word has been spoken, and the response is recorded and used for deriving and/or updating the learner model to capture the learner's proficiency of the word. In one embodiment, the system may interrupt and relate the current word to a context in a previous recent interaction with the learner that included the word.

In one specific example the learning objective is knowledge and expressiveness of the word Farm. An active listening mode interjection may be tap on the screen each time the word farm is spoken. For example, tap on the screen every time you hear a moo moo sound. A selection activity interjection may be: Which of these pictures show a farm?; Which of these animals can be found on a farm?; Say the word “Farm”; Which of these sounds does a cow make? Who makes the sound oink oink?

In one embodiment, the system and method disclosed herein may be implemented on a cloud computing service. Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

Referring now to FIG. 4, illustrative cloud computing environment 50 is depicted. As shown, cloud computing environment 50 includes one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 54A, desktop computer 54B, laptop computer 54C, and/or automobile computer system 54N may communicate. Nodes 10 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 50 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A-N shown in FIG. 4 are intended to be illustrative only and that computing nodes 10 and cloud computing environment 50 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

Referring now to FIG. 5, a set of functional abstraction layers provided by cloud computing environment 50 (FIG. 4) is shown.
